چکیده
A molecular and serological survey of selected viruses in free-ranging wild ruminants was conducted in 13 different districts in Iran. Samples were collected from 64 small wild ruminants belonging to four different species including 25 Mouflon (Ovis orientalis), 22 wild goat (Capra aegagrus), nine Indian gazelle (Gazella bennettii) and eight Goitered gazelle (Gazella subgutturosa) during the national survey for wildlife diseases in Iran. Serum samples were evaluated using serologic antibody tests for Peste de petits ruminants virus (PPRV), Pestiviruses [Border Disease virus (BVD) and Bovine Viral Diarrhoea virus (BVDV)], Bluetongue virus (BTV), Bovine herpesvirus type 1 (BHV-1), and Parainfluenza type 3 (PI3). Sera were also ELISA tested for Pestivirus antigen. Tissue samples including spleen, liver, lung, tonsils, mesenteric and mediastinal lymph nodes and white blood cells (WBCs) were tested using polymerase chain reaction (PCR) for PPRV, Foot and Mouth Disease virus (FMDV), Pestivirus, BTV, Ovine herpesvirus type 2 (OvHV-2) and BHV-1. Serologic tests were positive for antibodies against PPRV (17%), Pestiviruses (2%) and BTV (2%). No antibodies were detected for BHV-1 or PI3, and no Pestivirus antigen was detected. PCR results were positive for PPRV (7.8%), FMDV (11%), BTV (3%), OvHV-2 (31%) and BHV-1 (1.5%). None of the samples were positive for Pestiviruses.

Leishmania infantum, an etiologic agent of zoonotic visceral leishmaniasis (VL), is spreading in Iran. Dogs are the main reservoirs but L.infantum has been detected in jackals, foxes and wild rodents too. Despite high number of rodents in the world, the exact role of them in epidemiology of VL is not clear. In recent years the number of sporadic cases of dogs and humans VL has been increased in...

Pest des petits ruminants (PPR) is one of the important viral diseases of goats and sheep. The viral agent of PPR, Small ruminant morbillivirus (SRM), has been shown to infect several species among domestic and wild ruminants. In order to investigate the occurrence of SRM infection in Water Buffalo (Bubalus bubalis), blood samples were collected from 150 buffaloes (98 males, 52 females) referre...

In order to study the seroprevalence of pestivirus infection in small ruminants of Ahvaz at Khouzestan province of Iran, 148 sheep sera and 143 goat sera were randomly collected and tested by seroneutralization. Seroneutralization was performed by NADL strain of Bovine viral diarrhea virus genotype 1. The results indicated the overall seroprevanelces of 46.62% in sheep and 32.871% in goats. Pre...
